Assembly

NOTE: It is suggested to remove the battery, S Pen, SD
Card, and SIM card (if your phone uses a SIM card).
Heat at a low degree such as less than 80 degree because the adhesive is not so
strong. Heat makes it's easy, but you also can gave up heating and cut the
adhesive sticker directly. Please be careful.

Cut LCD screen adhesive sticker carefully and slowly.

Be very careful once you get to the bottom part of the phone, take your time,
and be very careful not to cut the flex of the Back and Menu buttons. Use the
next set of images to examine how close they are to the edge so you don't
accidentally cut them.

Insert the spudger underneath the LCD to cut the adhesive
in the middle part. The adhesive is strong so make sure you are underneath the
copper insulation before separating.

Notice 1: The adhesive is in the red line.

Notice 2: If you insert the spudger from right side, keep the length of the
tool in less than 2.2cm, which is for avoiding damaging the home button flex.
Notice 3: If you insert the spudger from left side, keep the length of the tool
in less than 4.4cm for the same reason.

Notice 4: Pay attention to the part with LCD screen flex.
When you cut the adhesive, leave the top part alone to avoid damage the flex.
But if it's the broken screen, you don't need to worry so much.

Be careful with the bottom side because there are the soft keys. If the
adhesive in the red line don't function any more when you place the new LCD
screen, you can choose to use the 3M double side tape. It can help to fasten
the new screen together with the LCD screen sticker.

Release S Pen touch sensor film connector and LCD screen connector.

Remove the LCD screen finally.

Remove back cover easily. And take away the battery, SIM
card and S Pen by the way.

Remove all together 16 screws from middle housing.

Free the clasps along the battery slot. And the push the
front assembly out from middle housing with effort.

We can see the USB board but we can't tear it down directly. Because 1. The USB
board flex connector is connecting on the back of the motherboard. 2. If want
to remove motherboard, the LCD screen need to be removed at first. 3. The USB
board assembly comes with two touch keys together but they are placed under the
touch panel. So we have to remove the motherboard and LCD screen at first next.

securing USB board and motherboard.

Release all the connectors connecting with motherboard.

Pry up the motherboard and release USB board connector
from back.
